The 3.0 release page on GitHub has more details including screenshots. But for those that have a few minutes to spare, I also prepared a demo video showing off the new stuff, as well as a brief tour at the end about what makes IntelliJ such a powerful tool for writing Elm code.

intellij-elm supports both Elm 0.19 and 0.18, it runs on Mac/Windows/Linux, and—when used with IntelliJ Community Edition—it’s 100% free and open-source.

Thank you to all the contributors who made such a big impact in this release. If you have questions/feedback/problems, please reach out to me on Discourse/Slack/Github (or even by email!).

This sounds awesome! Does the improved elm-format support mean that it is no longer necessary to use a paid version of IntelliJ to get automatic format-on-save? (I’d be happy to pay for IntelliJ for myself, but having full support for Elm in the community edition makes it a lot easier to recommend to beginners as a “getting started with Elm” IDE.)
